Compact and reliable
Fits perfectly into my custom water monitoring box. The probe feels durable. Only minor issue is the cable could be slightly longer for some deep tank applications.

Excellent documentation support
I was worried about the wiring, but the pinout is clearly labeled. The temperature compensation feature works well, providing stable conductivity data even when water temp fluctuates.

Great starter sensor
As someone new to electronics, I found this easy to set up. The community examples helped me get the serial data reading quickly. Highly recommended for beginners.

Professional grade performance
Using this for a small-scale water quality study. The data logging is smooth and the conductivity range covers most fresh water scenarios effectively.

Good accuracy, needs calibration
The build quality is solid and the digital output saves a lot of coding time. Just remember to calibrate it with standard solutions before first use for best results.

Perfect for my hydroponic setup
This sensor module integrates easily with my Arduino project. The TDS readings are consistent when compared to my handheld meter. Great value for the price.
Q: Does the package include calibration solutions?
A: No, the package includes only the sensor module and probe. Calibration solutions (such as 1413 µS/cm) must be purchased separately for accurate tuning.
Q: What is the warranty period for the probe?
A: The probe comes with a 6-month manufacturer warranty covering defects in materials and workmanship. Damage caused by improper voltage or physical abuse is not covered.
Q: How often does the probe need cleaning?
A: For continuous immersion, we recommend inspecting and gently cleaning the electrode with a soft cloth and distilled water every 2-4 weeks to prevent biofilm buildup which affects accuracy.
Q: Is this sensor compatible with Raspberry Pi?
A: Yes, it is compatible. Since it outputs a digital UART signal, you can connect the TX pin of the sensor to the RX pin of the Raspberry Pi GPIO, ensuring common ground.
Q: Can this measure saltwater conductivity?
A: This module is optimized for fresh water and low-salinity applications like aquariums and hydroponics. It is not recommended for high-salinity seawater measurements as it may exceed the linear range.
